Developmental studies were done at 3 and 4 years of age in a series of 656 children and the results were correlated with the preceding labor pattern and the type of delivery. It was determined that there were significant adverse effects among offspring delivered by midforceps procedures or born following labors characterized by prolonged deceleration, secondary arrest of dilatation, or arrest of descent.
对656名儿童进行了3岁和4岁时的发育研究，并将结果与之前的产程模式和分娩类型相关联。结果发现，中位产钳分娩的后代或在产程中出现长时间减速、继发性扩张停滞或下降停滞的后代存在显著的不良影响。
